Oops, yeah, boots. I was obviously distracted by the prospect of virility.

There's a jeans ad in an old Playboy I saw (from the 70s) that features OJ Simpson sitting on a chair, wearing jeans. Except if you look closely he has three legs. All with a boot on the end. It says "OJ DINGO" on top of him. The original 3 legged jeans. Weird though. If you do a search for the text you can find some variants.
